Paccar’s in-house engines power profit, for now

Paccar is expected to report its 77th consecutive year of net profit for 2015 once the final figures are in, and fundamentals remain strong. The company has paid a regular dividend for more than 70 years and has no debts on the manufacturing side of business, only on the finance and leasing division. Sales for 2016 are expected to come in about 13% ahead of prior year figures and just slightly below the record set in 2006. As of September 2015, it had US$2.1bn in cash. What's the secret to its success?
